Compositing in After Effects and Fusion makes different demands than node-based compositing in Nuke, and the two apps themselves diverge. After Effects is famous for two things: an appetite for RAM (for RAM previews and its layer-based model) and a love of CPU cores for multi-frame rendering. Fusion, being node-based, leans more on the GPU like its sibling DaVinci Resolve. The ideal workstation serves both behaviours. This guide covers the ideal After Effects and Fusion compositing PC for Nigeria.
It complements our Nuke/Fusion VFX build and the Cinema 4D motion graphics guide — motion designers often run AE and C4D together.
After Effects' Two Appetites
- RAM for previews: AE caches frames in RAM for smooth playback, so more RAM means longer real-time previews. This is the classic AE bottleneck — see how much RAM you need.
- CPU cores for multi-frame rendering: AE's multi-frame rendering uses multiple CPU cores (and lots of RAM) to render several frames at once, so cores and memory together speed exports.
- GPU for accelerated effects: a capable GPU accelerates many effects and playback.
Fusion's Different Demands
Fusion, like Nuke and Resolve, is node-based and GPU-accelerated, so a strong GPU with good VRAM matters more for it than for AE. Building for both means not skimping on the GPU even though AE's headline needs are RAM and CPU.
The Recommended Spec
- RAM: 64GB is the comfortable target for AE (32GB is a tight minimum) — the single most impactful component for After Effects.
- CPU: a modern high-core CPU (8–12+ cores) to exploit multi-frame rendering.
- GPU: a capable RTX card with good VRAM — important for Fusion and AE's GPU-accelerated effects.
- Storage: a fast NVMe SSD for the disk cache and media — AE's cache benefits from fast storage when RAM fills.
- Display: a colour-accurate monitor for compositing (colour-accurate monitors).
The Nigeria-Specific Notes
- RAM is the priority spend: for After Effects, more RAM transforms the experience more than almost any other upgrade — prioritise it.
- Power protection: a complex composition or a long render deserves UPS protection (power optimisation).
- Cooling for renders: multi-frame rendering pegs all cores — cool it well for our climate.
Frequently Asked Questions
Why is After Effects so RAM-hungry? Because it caches frames in RAM for smooth previews and uses RAM heavily during multi-frame rendering. More RAM means longer real-time previews and faster exports, making memory the single most impactful component for AE — 64GB is the comfortable target.
Does After Effects use multiple CPU cores? Yes — its multi-frame rendering renders several frames simultaneously across multiple cores (using lots of RAM to do so). A higher core count, paired with ample RAM, speeds exports significantly.
How is Fusion different from After Effects to spec for? Fusion is node-based and GPU-accelerated (like Resolve), so it leans more on the GPU and VRAM, whereas After Effects' headline needs are RAM and CPU cores. A build for both should be strong on RAM, cores, and the GPU alike.
The One Thing to Remember
An After Effects and Fusion workstation is built on RAM first (64GB for AE's previews and multi-frame rendering), a high-core CPU to exploit that rendering, and a capable RTX GPU with good VRAM for Fusion and accelerated effects — plus fast NVMe cache and a colour-accurate display. In Nigeria, prioritise RAM above all, cool it for sustained renders, and protect complex comps on a UPS.
